Abstract
A key punch apparatus is provided for selectively removing notches of material from a key blank. The apparatus includes a punch and die subassembly which is rotatable between first and second positions. A carrier holds the key blank in an operative relation with the subassembly. An actuating handle is operatively coupled to the punch to cause an axial cutting stroke. Cutting a notch with the subassembly in the first position results in a notch having a first shape, while cutting a notch with the subassembly in the second position results in a notch having a second shape.
